Seat Belt Systems
Seat Belt Pretensioner
and Load Limiting
Systems For optimum protection, the driver and
passenger seat belts are equipped with
pretensioner and load limiting systems.
For both these systems to work properly
you must wear the seat belt properly.
Pretensioners:
When a collision is detected, the
pretensioners deploy simultaneously with
the air bags.
For deployment details, refer to the SRS
Air Bag Deployment Criteria (page
2-34 ).
The seat belt retractors remove slack
quickly as the air bags are expanding.
Any time the air bags and seat belt
pretensioners have fired they must be
replaced.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Warning/Indicator Lights on page
4-26 .
Refer to Air Bag/Seat Belt Pretensioner
System Warning Beep on page 7-48 .
(With Passenger Occupant
Classification System)
In addition, the pretensioner system for
the passenger, like the front and side
passenger air bag, is designed to only
deploy when the passenger occupant
classification sensor detects a passenger
sitting on the passenger's seat.
For details, refer to the passenger occupant
classification sensor (page 2-37 ). Load limiter:
The load limiting system releases belt
webbing in a controlled manner to reduce
belt force on the occupant's chest. While
the most severe load on a seat belt occurs
in frontal collisions, the load limiter has
an automatic mechanical function and
can activate in any accident mode with
sufficient occupant movement.
Even if the pretensioners have not fired,
the load limiting function must be checked
by an Authorized Mazda Dealer.
WARNING Wear seat belts only as recommended in
this owner's manual:
Incorrect positioning of the driver and
passenger seat belts is dangerous.
Without proper positioning, the
pretensioner and load limiting systems
cannot provide adequate protection
in an accident and this could result in
serious injury. For more details about
wearing seat belts, refer to "Fastening
the seat belts" (page 2-10 ).
Have your seat belts changed
immediately if the pretensioner or load
limiter has been expended:
Always have an Authorized Mazda
Dealer immediately inspect the seat
belt pretensioners and air bags after
any collision. Like the air bags, the seat
belt pretensioners and load limiters
will only function once and must be
replaced after any collision that caused
them to deploy. A seat belt with an
expended pretensioner or load limiter
is still better than wearing no seat
belt at all; however, if the seat belt
pretensioners and load limiters are not
replaced, the risk of injury in a collision
will increase.

2 –15 Essential Safety Equipment
Child Restraint
Child-Restraint PrecautionsMazda strongly urges the use of child-restraint systems for children small enough to use
them.
You are required by law to use a child-restraint system for children in the U.S. and Canada.
Check your local and state or provincial laws for specific requi rements regarding the safety
of children riding in your vehicle.
Whatever child-restraint system you consider, please pick the appropriate one for the age
and size of the child, obey the law and follow the instructions that come with the individual
child-restraint system.
A child who has outgrown child-restraint systems should use seat belts, both lap and
shoulder. If the shoulder belt crosses the neck or face, move the child closer to the center of
the vehicle.
A rear-facing child-restraint system should NEVER be used on the passenger seat with the
air bag system activated.
(With Passenger Occupant Classification System)
To reduce the chance of injuries caused by deployment of the passenger air bag, the
passenger occupant classification sensor work as a part of the s upplemental restraint system.
This system deactivates the passenger front and side air bags and also the passenger seat belt
pretensioner system when the passenger air bag deactivation indicator light illuminates.
When an infant or small child sits on the passenger seat, the system shuts off the passenger
front and side air bags and seat belt pretensioner system, so make sure the passenger air bag
deactivation indicator light illuminates.
For more details, refer to "Passenger occupant classification se nsor" (page 2-37 ).

2 –18 Essential Safety Equipment
Child Restraint Seating a child in a child-restraint system on the passenger seat is dangerous under
certain conditions (With Passenger Occupant Classification System):
Your vehicle is equipped with passenger occupant classification sensor. Even with the
passenger occupant classification sensor, if you must use the passenger seat to seat a
child, using a child-restraint system on the passenger seat under the following conditions
increases the danger of the passenger air bag deploying and could result in serious injury
or death to the child. 
The passenger air bag deactivation indicator light does not illuminate when seating a
child in the child-restraint system. 
Luggage or other items are placed on the seat with the child in the child-restraint
system. 
The seat is washed. 
Liquids are spilled on the seat. 
The passenger seat is moved backward, pushing into luggage or other items placed
behind it. 
Luggage or other items are placed between the passenger seat and driver seat. 
An electric device is put on the passenger's seat. 
An additional electrical device, such as a seat warmer is installed to the surface of the
passenger seat.
Do not allow a child or anyone to lean over or against the side window of a vehicle with
side air bags:
It is dangerous to allow anyone to lean over or against the side window, the area of the
passenger seat from which the side air bags deploy, even if a child-restraint system is
used. The impact of inflation from a side air bag could cause serious injury or death to an
out of position child. Furthermore, leaning over or against the door could block the side
air bags and eliminate the advantages of supplemental protection. Because the side air
bag deploys from the outboard shoulder of the seat, do not allow the child to lean over or
against the side window, even if the child is seated in a child-restraint system.
Never use one seat belt on more than one person at a time:
Using one seat belt for more than one person at a time is dangerous. A seat belt used
in this way cannot spread the impact forces properly and the two passengers could
be crushed together and seriously injured or even killed. Never use one belt for more
than one person at a time and always operate the vehicle with each occupant properly
restrained.
Always use a child-restraint system designed for use without a tether or the LATCH
lower anchor:
Using a child-restraint system that requires a tether or the LATCH lower anchor is
dangerous. Your Mazda does not have a child-restraint tether or the LATCH lower anchor.
The child-restraint system cannot be properly secured. In a collision, it could move and
injure other occupants as well as result in serious injuries or death to the child.

2 –26 Essential Safety Equipment
SRS Air Bags Sit in the center of the seat and wear seat belts properly:
Sitting too close to the side air bag modules or placing hands on them, or sleeping up
against the door or hanging out the windows is extremely dangerous. The side air bags
inflate with great force and speed directly expanding along the door on the side the car is
hit. Serious injury could occur if someone is sitting too close to the door. Give the side air
bags room to work by sitting in the center of the seat while the vehicle is moving with seat
belts worn properly.
Do not attach objects on or around the area where driver and passenger air bags
deploy:
Attaching an object to the driver and passenger air bag modules or placing something in
front of them is dangerous. In an accident, an object could interfere with air bag inflation
and injure the occupants.
Do not attach objects on or around the area where a side air bag deploys:
Attaching objects to the seat in such a way as to cover the outboard side of the seat in any
way is dangerous. In an accident the object could interfere with the side air bag, which
inflates from the outboard side of the seats, impeding the added protection of the side air
bag system or redirecting the air bag in a way that is dangerous. Furthermore, the bag
could be cut open releasing the gas.
Do not hang net bags, map pouches or backpacks with side straps on the seats. Never use
seat covers on the seats. Always keep the side air bag modules in your seats free to deploy
in the event of a side collision.
Do not touch the components of the supplemental restraint system after the air bags
have inflated:
Touching the components of the supplemental restraint system after the air bags have
inflated is dangerous. Immediately after inflation, they are very hot. You could get burned.
Never install any front-end equipment to your vehicle:
Installation of front-end equipment, such as frontal protection bar (kangaroo bar, bull
bar, push bar, or other similar devices), snowplow, or winches, is dangerous. The air bag
crash sensor system could be affected. This could cause air bags to inflate unexpectedly,
or it could prevent the air bags from inflating during an accident. Occupants could be
seriously injured.
Do not modify the suspension:
Modifying the vehicle suspension is dangerous. If the vehicle's height or the suspension is
modified, the vehicle will be unable to accurately detect a collision resulting in incorrect
or unexpected air bag deployment and the possibility of serious injuries.

2 –27 Essential Safety Equipment
SRS Air BagsDo not modify a door or leave any damage unrepaired. Always have an Authorized
Mazda Dealer inspect a damaged door:
Modifying a door or leaving any damage unrepaired is dangerous. Each door has a side
crash sensor as a component of the supplemental restraint system. If holes are drilled in
a door, a door speaker is left removed, or a damaged door is left unrepaired, the sensor
could be adversely affected causing it to not detect the pressure of an impact correctly
during a side collision. If a sensor does not detect a side impact correctly, the side air bags
and the seat belt pretensioner may not operate normally which could result in serious
injury to occupants.
Do not modify the supplemental restraint system:
Modifying the components or wiring of the supplemental restraint system is dangerous.
You could accidentally activate it or make it inoperable. Do not make any modifications
to the supplemental restraint system. This includes installing trim, badges, or anything
else over the air bag modules. It also includes installing extra electrical equipment on or
near system components or wiring. An Authorized Mazda Dealer can provide the special
care needed in the removal and installation of seats. It is important to protect the air bag
wiring and connections to assure that the bags do not accidentally deploy, and that the
passenger occupant classification system and the seats retain an undamaged air bag
connection.
Do not place luggage or other objects under the seats:
Placing luggage or other objects under the seats is dangerous. The components essential
to the supplemental restraint system could be damaged, and in the event of a side
collision, the appropriate air bags may not deploy, which could result in death or serious
injury. To prevent damage to the components essential to the supplemental restraint
system, do not place luggage or other objects under the seats.
Do not operate a vehicle with damaged air bag/seat belt pretensioner system
components:
Expended or damaged air bag/seat belt pretensioner system components must be
replaced after any collision which caused them to deploy or damage them. Only a trained
Authorized Mazda Dealer can fully evaluate these systems to see that they will work in
any subsequent accident. Driving with an expended or damaged air bag or pretensioner
unit will not afford you the necessary protection in the event of any subsequent accident
which could result in serious injury or death.
Do not remove interior air bag parts:
Removing any components such as the seats, front dashboard, the steering wheel,
containing air bag parts or sensors is dangerous. These parts contain essential air bag
components. The air bag could accidentally activate and cause serious injuries. Always
have an Authorized Mazda Dealer remove these parts.

2 –31 Essential Safety Equipment
SRS Air Bags
How the SRS Air Bags WorkYour Mazda is equipped with the following types of SRS air bags. SRS air bags are
designed to work together with the seat belts to help to reduce injuries during an accident.
The SRS air bags are designed to provide further protection for passengers in addition to the
seat belt functions. Be sure to wear seat belts properly.
Seat Belt PretensionersThe seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal
collisions.
In addition, during a side collision, the pretensioner operates on the side in which the
collision occurs. The pretensioners operate differently depending on what types of air bags
are equipped. For more details about seat belt pretensioner ope ration, refer to the SRS Air
Bag Deployment Criteria (page 2-34 ).
Driver Air BagThe driver's air bag is mounted in the steering wheel.
When air bag crash sensors detect a frontal impact of greater than moderate force, the
driver's air bag inflates quickly helping to reduce injury mainl y to the driver's head or chest
caused by directly hitting the steering wheel.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-34 ).
(With Passenger Occupant Classification System)
The driver's dual-stage air bag controls air bag inflation in tw o energy stages. During an
impact of moderate severity, the driver's air bag deploys with lesser energy, whereas during
more severe impacts, it deploys with more energy.

2 –32 Essential Safety Equipment
SRS Air Bags Passenger Air BagThe passenger air bag is mounted in the passenger dashboard.
The inflation mechanism for the passenger air bag is the same as the driver's air bag.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-34 ).
(With Passenger Occupant Classification System)
In addition, the passenger air bag is designed to only deploy when the passenger occupant
classification sensor detects a passenger sitting on the passeng er's seat. For details, refer to
the passenger occupant classification system (page 2-37 ).
Side Air BagsThe side air bags are mounted in the outboard sides of the seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the
system inflates the side air bag only on the side in which the v ehicle was hit. The side air
bag inflates quickly to reduce injury to the driver or passenger 's head and chest caused by
directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to "SRS Air Bag Deployment Criteria"
(page 2-34 ).
